Starts cold. Go to store shut off come back in 3 minutes ...won't start.

What is your question?

Starts cold... Drive 10 blocks...shut off come back in 3 minutes won't start. I can wait 20 minutes it will start Or I can change coils and it starts right away. I am guessing but either the computer box or some sensor is saying. Coil too hot... not starting... I keep studying... But no clue... I have new coil ... Igniter... Plugs and wired

What makes this problem better or worse?

Cool off or change coil
